In this example I'll use a project with WebAPI, described in this page Entity Framework missing FAQ (Part 4). From EF Code First class definition to WebAPI2 on VB.NET
1. npm install -g @angular/[email protected]
2. ng new Angular --skip-tests --style=scs
3. Include Angular files to project

32: \Angular\src\assets\.gitkeep
33: \Angular\src\environments
34: \Angular\src\environments\environment.prod.ts
35: \Angular\src\environments\environment.ts
4. Delete app-routing.module.ts and its references in app.module.ts and app.component.html
5. Tune outputPath in Angular frontend and Include result of Angular frontend to ASP.NET MVC project
25: ' Angular bundles
26: bundles.Add(New ScriptBundle("~/bundles/Angular").Include(
27: "~/bundles/AngularOutput/inline.*",
28: "~/bundles/AngularOutput/polyfills.*",
29: "~/bundles/AngularOutput/scripts.*",
30: "~/bundles/AngularOutput/vendor.*",
31: "~/bundles/AngularOutput/runtime.*",
32: "~/bundles/AngularOutput/main.*"))
33:
34: bundles.Add(New StyleBundle("~/Content/Angular").Include(
35: "~/bundles/AngularOutput/styles.*"))
36: End Sub
37: End Module
6. Add Controller and View to MVC project in order to show Angular result
1: @Code
2: ViewBag.Title = "Index"
3: End Code
4:
5:
6: @Styles.Render("~/Content/Angular")
7:
8: <app-root>test</app-root>
9:
10: @Scripts.Render("~/bundles/Angular")
11:
7. Add in top menu special point to show Angular result
8. Start Angular engine from Angular folder: ng build --extractCss --watch
9. Start project and check - is angular engine is working?
Ups, there small mistake with view name, fix it and recheck now.
